This idea of truth was told through a Where's Waldo book. The four categories of knowing truth (by perception, what you're told, feeling, and reason) were all tested in this concept of truth. It showed how each concept could be or not be used and show the truth. People assume there is a Waldo because they are told he is there; perception is used to search for Waldo in every scenario; some often have a feeling of where he is and therefore begin their search in that area; many use reason to track Waldo down, by starting along the edges and keeping a keen eye for red and white stripes. All are valid ways of finding the truth of where Waldo is, yet none can ever truly be relied on in finding him.
